Nanoscale science based on one-dimensional structures has found a springboard in the discovery of carbon nanotubes. Since then, many different materials have been produced as one-dimensional (1D) nanostructures, for example nanotubes and nanowires. We investigate novel size- and shape-dependent crystals and the properties of nanoscale materials.
For the production of inorganic nanostructures, we use hydrothermal processes which provide suitable synthetic routes for material preparation under mild conditions. In a typical reaction, reactants are poured into the Teflon vessel. Afterward, the autoclave is heated to a temperature up to 250 °C and under autogenic pressure as high as 40 bars.

We produce a broad range of materials TiO2, ZnO and V2O5 nanofilaments as well as KNbO3 [1, 2] and LiNbO3 nanowires . Few illustrations are given below
